This is totally inconsistent with the proposal in the OP.
He is talking about going into the future and taking an item back in time... not changing the past. Of course you can make arguments that there will still be connections or whatever, but I think you just missed one key difference upon a brief inspection.
Edit: ahole-surprise beat me to the grandfather paradox.
The other paradox mentioned is known as the twin paradox: if one were to travel near the speed of light, they would age slower than usual to someone in Earth's reference frame, yet the person on Earth would appear to age slower to the person traveling near the speed of light.
G5, if you went back in time to pick up the $100 bill, would you not see yourself pick up the $100 bill as you laid it down 1 year ago?
Wouldn't this mean that you already know you would go back in time to pick up the $100 bill?
This also means that there would be two of you existing at the same point in time; one of you would have just placed down the $100 bill, and the other would've just went back in time to grab the $100 bill.
You cannot go back to grab $100 bills at earlier and earlier points on the timeline, because taking the bills at an ealier point in time would mean that the bill would not exist at a later point in time when you went back to grab the bill.
What you are assuming is that there are infinite universes, and that everytime you go back to take a bill, you are actually shifting into a different universe. By altering each universe by taking the bill at different points in time, you are actually creating more sets of infinite universes for each universe that you visited; each set of universes would have the bill being taken at a different point in time.
Therefore, yes, you can obtain limitless amounts of bills, but not in the same way that you thought.

He is going forwards in time to get the bill, not backwards.
I was out having a smoke, pondering in my thoughts and started thinking about time travel. Suppose we made a time machine, which according to some recent study, is very possible and people are already making time travel machines which should theoretically work using lasers to bend matter in a circle, creating a "worm hole" which should allow you to go back in time. But theoretically, it will only allow you to go back as far as the time that the machine was turned on. This doesn't conflict with my idea though.
So here is my theory, suppose you could go back in time. Now say you have a 100$ bill sitting on a table for a year or so. You pick up the 100$ and then go back in time, with the 100$ in your wallet, to the end of that year when the 100$ bill is sitting on the table. Theoretically, since at that point in time, since you still haven't moved the 100$, it should still be there on the table, with it being in your pocket as well.
I figure you could repeat this process, always moving a little bit further back in time to pick up the 100$ bill, basically duplicating it through time travel over and over. Theoretically you would have to move a little bit further back in time because if you return to a time which is later then a previous time you picked up the 100$ bill, it may not be there at all.
If this works, it could solve all resource problems. You could do this with Metals, Liquids, Gas, Medicine, basically anything.... And what excites me the most about this theory is that we could duplicate anti-matter particles. We can make anti-matter in labs but to make a handful of them would bankrupt the world. Anti-matter is one of, if not the best sources of energy in the universe that we know of and if you could make 1 anti-matter atom and then duplicate it over and over, we could power the world for virtually nothing and make long distance space travel a very real possibility.
Didn't Stephen Hawking said that time travel didn't exist based solely on the fact that if it did exist, we would be flooded already with time tourists? Like, it would only be possible to not have had contact already with time tourists if we were the more advanced time line of all, that being statistically almost impossible, given there should be infinity time lines or something like that.

As soon as you pick up the 2nd one, does the 1st one disappear because as soon as you picked it up the 2nd time, it wasn't there for you to pick it up the 1st time. Or does it make another dimension in which case makes the 1st theory plausible. When you go back in time, is there 2 of you in the world? Would you actually be cloning yourself? I would assume the answer is yes but who knows... It is really mind boggling when you get deep into it.

Do you have a source for this? I was arguing about the possibility of time travel with a friend and if you have a valid source I'd like to rub it in his face

oh dear. Who let the (pseudo-scientists) out? Stuff like this rests easier on philosophy than science. But then you'd have to have regard to A and B theories of time, which i'm sure someone out there has a clearer idea of it than me.

Yeah except I said it before him in this very thread.
